1. Mauna Kea Observatory Jordan Matayoshi Shae Otsuka

2. It’s a 4,200 meter high summit of Mauna Kea Hawaii houses the world's largest observatory

3. Research used for optical, infrared, and submillimeter astronomy.

4. There are 13 working telescopes at the summit

5. Nine of them are for optical and infrared three of them are for submillimeter wavelength one is for radio astronomy

9. Geography Stationed on a dormant volcano Altitude is 4205m (13,800ft) Summit about 40% above of the Earths atmosphere

10. Why it is a unique site Atmosphere about mountain is extremely dry important for measuring infrared and submillimeter radiation from celestial source Cloud free Away from city lights
